Vegetable Oil as Vehicle Fuel

Biofuel isn't turning out to be quite as glorious as we'd hoped. It's great fuel, but it's also a valuable cash crop. Valuable enough for some farmers to screw up their environment for a quick buck.

It would be tragic if biofuel, instead of being a great green hope, turned out to be this year's strip-cleared rainforest eco-crime. Until I've run the numbers, I am therefore removing these instructions.
